To all whom it may concern:

Be it known that I, DONALD BARNS MORISON, a subject of the King'of GreatBritain and Ireland, residing at Hartlcpoohin the county of Durham,England, have invented Improvements in Apparatus for Separating Oil andWater From Steam Before it is Condensed, of which the following is aspecification.

This invention relates to apparatus for separating oil and water fromsteam before it is condensed, and particularly to steam cleansing andcondensing apparatus with steam winches, steering engines, steam pumpsand other auxiliary engines in which oil is freely used and where suchoil if it should pass into the boilers with the feed water, will be asource of danger by causing overheatingof furnaces, and will decreasethe efliciency of the heating surfaces In such apparatus the cleansingand condensing of the steam may advantageously be effected in onecombined structure in order to obtain high efficiency of cleansing andcondensing, a minimum of weight, and the occupation'of a' minimum ofspace, which, on shipboard, are features of great importance. Such acompound apparatus may conveniently comprise a vessel or casingconstructed with compartments or chambers that are in communication witheach other in such a manner that steam admitted to the first chamber canflow-through the succeeding chamber or chambers in such a manner as tosweep practically through.

every part of the chambers, the first chamber or the first and one ormore succeeding chambers being provided with devices that are arrangedto ofier alarge surface to the steam flowing chambers and are adapted todistribute such steam throughout the width and length of the chamber orchambers and to separate and collect oil. and water an oil and watercollecting receptacle, and the delivery end of the chamber or of thelast cleansing chamber, with the condensing portion an opening oropenings that cally throughout the length extends orextend practiof thecondenser between thetube plates so that a practically uniform flow ofcleansed and dry steam will take place from the cleans ing portion ofthe apparatus to the condensing or .heating portion thereof.

My invention may be applied to various types of surface and directcontact condensers. By way of example, I will describe it in connectionwith surface condensers such as those used on steam ships for condensingthe steam from auxiliary steam engines and usuall termed winch orauxiliary condensers.

In the accompanying illustrative drawings, Figure l l is a transversesection, and Fig. 2 a plan partly in horizontal section-0n 'the line A Aand partly on the line through the chamber or being in communicationofthe apparatus through B B of Fig. 1, showing one constructionof combinedcleansing and condensing apparatus according to this i invention. Fig. 3is a vertical section, corresponding i to the line C C of Fig. 1, but toa larger scale, showing some of the steam distributing and oil and watersepaf' rating and collecting devices. Figs. 4 and *5 are sectionaldetail views showing modifications. Fig. 6 is a perspective view showinga modified arrangement of the apparatus. Fig. 7 shows partly in verticalsection and partly in front elevation, Fig. 8 partly in plan and partlyin horizontal section, and Figs. 9 and 10 in cross section on the linesE E and F F respectively of Fig. 7, one construction of steam cleansingapparatus according to this invention for use separately'fiom acondenser.

Referring to Figs. 1, 2 and 3, along one side, front side, and extendingpractically the whole length and depth of the casing l of the apparatusis formed a chamber 2 (hereinafter called for distinction the cleansingchamber) which contains the steam distributing and oil and waterseparating and collecting devices, hereinafter described, and isprovided with a steam inlet 3, the front of the chamber 2 being providedwith a removable cover I 4 which enables the interior of the chamber tobe easily and quickly inspected and cleaned. The steam distributing andoil andv water separating and collecting devices are arranged so thatoil and water separated from the steam flowing through the cleansingchamber 2 can drain into a receptacle 5 at the bottom of the chamberthrough suitable passages 6 in the cover 4. 7 is a communicating passagebetween the cleansing 2 and the next adjacent chamber chamber 8 of thecondensing portion of the apparatus, the said passage eirtendingpractically the entire length of the cleansing chamber, and thereforethe entire length of the condenser tubes 9, thereby maintaining auniform velocity of flow from the cleansing chamber and facilitatinguniform deposition of oil and water on the various surfaces in avoidingthe creation of eddies and the disturbing influences of locallyincreased velocities, and also increasing the efficiency of thecondensing surfaces by insuring a uniform' flow of steam over suchsurfaces. This uniform flow of the steam through cleansing chamber,particularlyfi'om the said chamber is a feature of considerablepractical value, as it avoids any local discharge of steam fromtheehamber which would cause a disturbance of flow that would tend tosweep away any fine globules of oil and water which would otherwise bedeposited, and also to pick up particles of oil and water that had beendeposited and carry them off, and thus interfere with the efiiciency ofthe apparatus. The condenser in the example of apparatus shown, is ofthe multiple compartment type say the and from the having condensingtubes 9 through arrangement may be used.

- be divided up into a number of streams.

I and water that may be separated in the gupon lugs 10 onthe plates.

The oil and water separating devices comprise, as shown more clearly inFig. 3, vertical plates 10 carried by the plates or diaphragms l3and-against the opposite sides 0i which steam flowing through the guideslots 12 in the plates or diaphragms 13 is caused to impinge at such anangle as will facilitate the deposition thereon of oil and water fromthe steam without causing any undue back pressure or resistance to flowoi the steam. The oil and water collecting devices comprise horizontalor slightly inclined liquid collecting troughs or channels 11 supportedat the lower ends of the plates 10. Each diaphragm 13 is in the form ofa portable tray supported, like a shelf, in a slightly inclined posithesides of the cleansing chamber tion, upon ledges at 2 so that, on theremoval of the cover 4, the diaphragms with separating and collectingdevices 10-11 can be 1 easily withdrawn and cleaned. The top of eachdiaphragrn is formed with transverse oil and water collecting channels16 that drain into a longitudinal 'channel 16 (Fig. 1) which is incommunication through passages 16 in the cover '4 with the drainpassages 6, so that oil channels 16 can readily, drain through thepassages mentionedinto the receptacle 5. The guide slots 12 are iormed'mdownward extensions 13" of the diaphragm 13 and are so inclined to theplates lll that from such plates clear of the troughs 11 below, so thatsuch troughs will not offer any. serious obstruction to the flow oi thesteam through the The troughs 11 are of Y shape cleansing chamber 2. andare made separate from the vertical plates 10 from which they aresupported by engaginghook-like supports 11 at their ends The lower endsof each set oi troughs 11 are arranged to discharge into a gutter 15that'iis carried by the inner side of the cover 4 andis in communicationthrough holesfli in the cover with the drain passages 6 so that theseparated oil and water can drain from the troughs into the receptacle5. The number of steam distributing diaphragms 13 and sets ofliquid.separatingand collecting devices 10.11 used therewith, willdepend on the amount of oil in the steam and the degree. of extractionthereof desired.

Steam distributing-and oil and water separating and collecting-devicesof the kind hereinbefore described can be, constructed in various forms.Thus, in Fig.

spending Tdiaphragm 13, .and' the metal around such 'slots lis-extendedupward to form channels 16, 16 in of the diaphragm. .lilso, each liquidthe 1 upper side collecting trough'll is formed in one piece with the"corresponding supporting plate 10,'the two portions ofeach troughatopposite sides of the plate, being connected together:

' InFig. 5, each o the steam fiowing through' them and impinging uponthe plates will be deflected formed singly in the corre-v faces of thetwo plates and deposit oil and water thcreon. The collecting troughs forthe oil and water separated by the separating deviccs ll) arc, in thiscase, formed by the collecting channels 16 in the top of the diaphragm13 below such separating tend into such channels as shown.

Fig. 6 is a perspective view showing combined steam cleansing andcondensing apparatus somewhat like that illustrated in Figs. 1 and 2,but wherein the water inlet and outlct branches l9 and 20 respectivelyare arranged at the top of the apparatus instead of at orposite endsthereof as in Figs. 1 and 2.

Steam cleansing apparatus with steam distributing the kind hercinbcforedescribed may also be construct-- ed separately from a condenser. Figs.7 to 10 inclusive show one arrangement of this kind. The exhaust steam,containing oil, enters the wedge shaped distributing chamber 3 by theinlet 3 and flows into the cleansing chamber 2 through the guide slots12 in the diaphragms 13 and over the separating and collecting devices10 and 11 which are constructed and arranged substantially as in Figs.1, 2 and 3, the separated oil and water passing through the drainpassages 6 into the receptacle 5, and the cleansed steam flowing fromthe cleansing chamber 2 through openings 7 extending practically theentire length of the chamber into a jacket or passage outlet chamber 22and thcnco to the cleansed steam outlet 22. The construction of thesteam inlet cham- 21 and a wedge shaped ber 3 of gradually decreasingcross sectional area in an inward direction from the steam inlet 3, andtheconstruction of the steam outlet chamber 22 of grad ually increasingcross sectional area in a direction towards the steam outlet 22,

particularly the latter- ,construction, is a feature of great practicalvalue as it 1 allows of a uniform flow of steam through and from thecleansing chamber 2 as and for the purpose hereinbefore described.
